Hello all! :)
I have a male crowntail betta with fin rot. I treated him in a Q tank for a week with aquarium salt and 75% water changes daily. This didnt seem to do much good. I also completely cleaned his tank while he was quarantined as I had a diatom and worm explosion due to an anacharis I purchased and did not properly clean before entering it into the tank. I finally got a gravel vacuum ( I had been doing pwcs by scooping out water ) and removed most of the substrate. I cleaned what i removed with vinegar but decided to just buy new gravel to make it easier. I was afraid I wasn't going to rinse all of the vinegar from the gravel. I vacuumed the bottom and removed almost all of the water. There was probably about 15% left after two thorough vacuumings. I cleaned the sides of the tank to remove any critters clinging there. I also rinsed all of my silk plants and decor with hot water, soaked in a vinegar solution, then rinsed with hot water and allowed to dry. This was to remove the slime covering it all ( Im guessing algae?) and all possible pests. I did this extreme cleaning also because my poor betta has developed fin rot, whether he had this already when I bought him I am not sure. It has gotten progressively worse since and so I decided it was time to make absolutely sure his tank was as pristine as possible. Afterwards I ran the filter for two days to cycle the bacteria from the sponge into the fresh tank water.
So, after treating with salt for a week with almost no visible improvement, I moved him back into his 10g tank. I also added a couple more silk plants for his enjoyment and relaxation. I purchased a couple medications for future problems as well as the current fin/tail rot. I bought maracyn oxy, jungle fungus clear "tank buddies" fizz tabs, and another Mardel medicine for ich and velvet ( cant seem to remember the name). I wasnt sure if I should use the Fungus Clear or Maracyn so I researched and read very good things about Maracyn oxy. I added the maracyn oxy (1/2 capfull) to his big tank and made sure to leave the filter off. I found it difficult to keep the ammonia down in his 1/2 gal Q tank even with 75% water changes daily. So I decided to use the big tank as it will be easier to keep the water perams in check. I use an Aqua-Tech 5-15 filter with biofiber and sponge with attached carbon.
The carbon is as old as the tank, about 2 months. I am wondering if this carbon will still remove the medication from his water allowing me to redose him and turn the filter off. I usually only run it for a couple-few hours a day. I dont like keeping the filter off to avoid the removal of the medication as the instructions say to continue filtration and oxygenation while medicating. So I want to treat him each day then filter it out at night. Also I am trying to understand if I do need to change the filter to get fresh carbon that will remove the medication how do I do so without causing a mini cycle and removing all of the good bacteria living in the sponge?
Any guidance is greatly appreciated! This is all so confusing. >.<
